https://community.cloudera.com/t5/Archives-of-Support-Questions/Capacity-Scheduler-Preemption-Timeouts/m-p/120293#M43036 <P>In the Fair Scheduler there are parameters for setting the algos that run preemption. This allows a window for containers to become available without killing them off. A standard is 300 seconds. I searched for a similar parameter in Capacity Scheduler using preemption but did not find it. Is there a back off period and if so what is that period? Is there a parameter to configure this window? </P> Sat, 08 Oct 2016 02:09:01 GMT wdailey 2016-10-08T02:09:01Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Capacity-Scheduler-Preemption-Timeouts/m-p/120293#M43036 <P>In the Fair Scheduler there are parameters for setting the algos that run preemption.

The default is 15 sec (15000 ms), see <A href="http://jp.hortonworks.com/blog/better-slas-via-resource-preemption-in-yarns-capacityscheduler/">here</A> and <A href="http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.3/bk_yarn_resource_mgt/content/preemption.html">here</A> for details.</P> Sun, 09 Oct 2016 09:14:00 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Capacity-Scheduler-Preemption-Timeouts/m-p/120294#M43037 pminovic 2016-10-09T09:14:00Z
